本論文研究開發的輸電鐵塔獨立基礎優化設計cad系統，以最小費用為目標，採用簡單、有效、易於編程的有約束非線性規劃方法? ?網格搜索法，對輸電鐵塔獨立基礎進行優化設計，確定出基礎埋深、基柱寬度、底板寬度、底板厚度等合理截面尺寸，並開發出計算、出圖一體化的優化設計計算機輔助設計系統。Because the different stiffness match of front and rear suspension is very influencing to the ride comfort, optimal model of ride comfort is developed, regarding the rms of driver ’ s acceleration as the objection, regarding the stiffness of front and back suspension as optimal variable, regarding quiet flexibility 、 dynamic flexibility 、 frequency and dynamic load as nonlinear constraints. by matlab program and using sqp, the optimal match of front and back suspension ’ s stiffness is achieved, this optimal model consider not only request of quiet 、 dynamic flexibility 、 frequency and damp, but also security of run and peace of road, it is closer to the fact than other models which only consider partial restriction
由於前後懸架垂直剛度的不同匹配對汽車行駛平順性影響較大，論文建立以駕駛員垂直加速度的均方根值作為汽車行駛平順性優化目標值、以前後懸架垂直剛度作為優化變量的優化設計模型，並輔以靜撓度、動撓度、頻率、動載荷等非線性約束，使用序列二次規劃法，利用matlab編制優化程序，求得前後懸架垂直剛度的最優匹配值;此優化模型不僅包含動靜撓度及頻率和阻尼的限制，還考慮到汽車的行駛安全性和道路友好性，比文獻報道的只考慮部分約束的優化模型更切合實際情況。Abstract : a general bpm simulator for optical waveguides is presented in this paper. this system includes three tools : the effective refractive index calculation tool, the waveguide mode solution tool, and the beam propagation method simulation tool. this system is very useful for the optimal design of the linear optical waveguide devices

電力系統用絕緣電纜及其輔助設備.額定電壓0 . 6 1kv的有束狀組合線圈的架空配電懸掛設備Institutional economics is its basic theoretical clue. the institutional approach includes : transaction cost is a basic view for housing finance institutions and a certain institution follows the principle of minimum transaction cost ; financial deepenness and financial function theories are important ways to understand housing finance institution ; a systematic institutional structure of housing finance comes from the interaction of social economy, culture and politics, and institutional bundling and embeddedness are common forms ; financial structure theory is a forceful quantitative way to analyses housing finance institutions ; minimization of transaction cost is the basic motivation for institutional transformation, and the basic ways are forced transformation and induced transformation ; equity and efficiency are basic criteria for evaluating housing finance institutions, which may implement through certain institutions while government acts as leverage between equity and efficiency. ( 2 ) multiformality and transformation of housing finance
制度經濟學是基本的理論線索，制度分析範式包括如下方面：交易成本是考察住房金融制度的基本視角，特定的住房制度安排遵循約束條件交易成本最小化原則；金融深化和金融功能理論是理解特定住房金融制度安排的重要輔助方法；整體性住房金融制度結構的形成是包括社會經濟、文化、政治等各類制度在內互相影響、平衡的產物，制度捆綁和制度嵌入是常見的形式；金融結構方法是用制度分析方法解釋住房金融制度的有力的定量分析工具；住房金融制度變遷的基本動因是交易成本最小化（外部收益內部化） ，變遷的基本方式是強制性變遷和誘致性變遷；公平和效率是住房金融制度評價的基本標準，公平和效率通過一定的制度安排可以同時實現，政府在住房金融制度中起著平衡公平和效率的杠桿作用。Green " s theorem is employed to find the quantity relationship among the constraints of heating rate, dynamic pressure and lift in reentry flight. the paper deduced the approximate solution of the optimal aeroassisted coplanar trajectories under the three typical constraints. the performance index to be minimized are either heat input, the total dynamic pressure, time during the atmospheric flight, the time integral of the square of the path inclination ; or maximize the time of flight during the atmospheric portion of the trajetory. an important conclusion is firstly obtained : under the three constraints above, the optimal aeroassisted coplanar transfers with the first forth kinds payoffs have the same optimal control laws
採用格林函數法，給出了同一平面氣動力輔助變軌飛行的3種過程約束（氣動加熱率、動壓、升力約束）條件之間關系的近似定量描述形成的飛行包絡線.由此求解了航天器同時受3種約束條件時，各種性能指標下的同一平面氣動力輔助變軌軌跡的近似解及相應的最優控制規律.文中對近似解與控制規律的內部結構作了細致的分析，得到了一些有益的結論分享友人
